2015-2019 was a precursor to actually exciting late summer fun (wildfires, smoke, and storms) and winters.
The lame summers seem to always follow with a garbage winter. Maybe it's just anecdotal but something I've felt in recent decades.
Maybe a year of lag before the results show.
Kinda depends on where you're talking about. At SEA, 3 of the past 6 Mays have had near or above normal precip. Looking at temps, the last two Mays have been cooler than OLM's long term average, and the only warm one the past 5 years was 2023.
The 2015-19 stretch was brutal, though.
The CFS has spoken for May. The precip prog looks kind of El Ninoey. Not sure if we can make the direct connection yet but in any case, it would be good news for the south given the widespread drought there.
